    I would make a capacitive QWERTY keyboard layout, with a small pad for each key. Something that could be unrolled onto any surface and used as a keyboard (or number keypad). Since the material is not only flexible, but clear as well, you could glue an EL panel to the back of it, and have a flexible, super-thin, backlit keyboard! Reminds me of Tony Stark’s keyboard. Or, you could stick this capacitive keyboard/keypad to a glass surface (eg. coffee table, car window) for a touch-sensitive overlay.

    Now that I think about it, capacitive touch sensing can be touchy, so in the spirit of spectra symbol, you could use the same materials that are inside the softpots, for resistance-based sensing instead.

    Also, krdarrah1234 has already mentioned a shoe insert, which was one of the first things that came to mind. Check out the Adidas Megalizer shoes (I’m not usually an e-textile guy, but this stuff is pretty cool): https://www.youtube.com/watch?v=p0LtpDFxHCQ

    Took me a bit to find some good references for this board, here’s what I found:

    Library for Arduino - works great with this module

    Video tutorial on calibrating the module - uses the above library

    Another note: I’m using this to replace the HMC6352, which is not tilt-compensated. The HMC6352 had a nice north-indicator arrow screenprinted onto the PCB, but this LMS303 board lacks that indicator…. So, to draw it on yourself: hold the board flat in front of you, with the chip on top, and rotate the board until the “SA0” marking is properly readable to you. The north-reference arrow should be drawn to point exactly towards the right-hand edge of the board.

    Hope that helps somebody else using this board!

    Worked great, thanks!

    I see that the settings are saved on a battery-backed RAM on the device. Is there a way to factory reset the module, perhaps by temporarily removing this battery?

  • Product GPS-00465 | about a year ago

    While trying to change the baud rate of this module, I think I mistakenly set the protocol to SiRF by sending this command:


    Now, I can’t get the TinyGPS library to read the incoming data at either 19200 baud or the default 4800 baud (which was working fine before I sent the command).

    How can I set this back to NMEA at 4800 baud?

No public wish lists :(
